·Sign legends accomplished with
either the direct or reverse silk screen process, or with black nonreflective
sheeting that is direct applied.

b) Ensure
the finished signs comply with the details specified in the contract documents.

2) Type B Signs.

a) Comply
with the following:

·Extruded aluminum highway sign
panels mounted on either wood or steel breakaway posts as specified in the
contract documents.

·Sign face material fabricated from
reflective sheeting.

·Sign legends accomplished through
use of reflectorized or nonreflectorized letters, numerals, symbols, and
borders that are direct applied.

b) Ensure
the finished signs comply with the details specified in the contract documents.

c) Prior
to fabrication, submit shop drawings for each Type B sign according to
Article
1105.03. Each drawing is to be a scale drawing of the sign face, showing the
size, arrangement, and spacing of all letters, numerals, symbols, and borders.

a. Accurately
erect all Type A and B signs to comply with the dimensions and details shown in
the contract documents. Obtain the Engineer’s approval for all deviations from
the contract documents before starting the work.

b. After
installation, modify each 4 inch by 6 inch (100 mm by 150 mm) wood sign post by
field drilling holes as shown in the contract documents. All labor and
equipment necessary for this modification is included in the price bid for the
post and no separate payment will be made.

d. Set
posts to full depth at the required spacing. Align posts accurately both
vertically and horizontally. Place backfill consisting of Class A crushed stone
meeting the requirements of Article 4120.04 into the post holes. Place material
in layers no more than 6 inches (150 mm) in depth. Thoroughly compact each
layer taking care to preserve the alignment of the posts.

e. Where
steel breakaway posts are specified in the contract documents, carefully drill
or dig footing holes to the required size at the proper location. Spread the
excavated earth within the right-of-way to blend uniformly with the existing
surface to the Engineer’s approval.

f. Immediately
before placing concrete, remove all loose and uncompacted material from the
bottom of the hole. Some of the holes will be located in the bottoms of
drainage ditches. In these cases conduct construction operations so that water
will not enter excavated holes.

g. For
the breakaway base, tighten all bolts to maximum using a 12 inch to 15 inch
(305 mm to 308 mm) wrench to bed washers and shims, and to clean bolt threads.
Loosen each bolt in turn and retighten in systematic order to the torque
specified in the contract documents. For the fuse plate assembly, tighten fuse
bolts to the torque specified in the contract documents.

h. Preposition
stub posts and reinforcing to the proper depth as shown in the contract
documents. Ensure stub posts and reinforcing are properly aligned and secured,
complying with Article 2405.03, H, 3. Cast the footing to the elevation shown
in the contract documents. Rod the concrete in place to fill all the voids.
Form the exposed portion of the footing as shown in the contract documents.
Shape the cap of the footing so that drainage is away from the base plate of
the post. Apply the provisions of Section 2403.

i. After
the concrete has developed the strength required by
Article 2403.03, N, 2,
attach the post and adjust for correct alignment and elevation. Remove all
excess concrete from around the holes.

j. Erect
extruded panels according to the details in the contract documents. Take
necessary measures to prevent damage to sign faces. Repair (at no additional
cost to the Contracting Authority) any mars, scratches, dents, or other damage
to sign faces visible at a distance of 5 feet (1.5 m). Tighten locknuts on the
post clip bolts by means of a torque wrench to 225 inch-pounds (25 Nm) when
using dry, clean, unlubricated threads. Draw the nuts on panel bolts tight.

b. Erect
markers and delineators so that the signs and delineator reflectors will be at
elevations called for in the contract documents. Ensure they are true to line
and grade and are truly vertical. Where a milepost marker is designated, attach
the marker in place of a delineator. Where a 6 inch by 6 inch (150 mm by 150
mm) route marker is designated, attach it above the milepost marker on the same
post.

c. Ensure
delineator posts for these signs are plumb and firm in the ground, spaced as
shown in the contract documents, and driven to the required lines and grades.
Ensure that after driving, the top of the post has substantially the same cross
section dimensions as the body of the post. Battered heads will not be
permitted. Remove from the site and replace (at no additional cost to the
Contracting Authority) all posts which are bent or otherwise damaged to the
extent that they are, in the Engineer’s opinion, unfit in the finished work.

3. Perforated Square
Steel Tube (PSST) Posts and Anchors.

a. Position posts within anchor at furthest corner from
likely point of impact from an errant vehicle.

b. Embed post within anchor without any play.

c. Provide minimum insertion length as required by
manufacturer.

d. Ensure inside of break-away and slip base anchors
installed in concrete are free of concrete to allow drainage.

e. Install triangular slip base assembly as required by
manufacturer.

C. Sign
Positioning.

The glossy surface on
sign faces may produce specular reflection. Position signs to eliminate or minimize
specular reflection in the following manner:

1. Overhead Signs.

a. Adjust
the sign face in the following manner, where the road grade approaching the
sign is plus 2.0% or greater:

·Vertical axis to be parallel to a
plumb line.

·Horizontal axis to be at right
angles to the road.

b. Adjust
the sign face in the following manner, where the road grade approaching the
sign is less than plus 2.0%:

·Vertical axis inclined to face
upward at the rate of 1/8 inch per foot (10 mm/m) of vertical sign surface for
each 1% the road grade differs from plus 2.0%.

·Horizontal axis to be at right
angles with the road.

2. Ground
Installations.

a. Ground
installations will be shown in the contract documents.

b. After
installation of signs is complete, the signs will be inspected at night by the
Engineer. If specular reflection is apparent on any sign, adjust its
positioning to eliminate or minimize this condition.

D. Sign Identification.

Identify the signs as
specified in Section 4186, with the following additions:

Measurement for signing,
satisfactorily erected according to the contract documents, will be as follows:

A. Type A Signs.

1. Calculated
in square feet (square meters) of sign area completed in place based on the
nominal dimensions of the signs.

2. The
area of all regular, rectangular, triangular, octagonal, and circular shaped
Type A signs will be measured from the nominal given dimensions. Cutouts for
rounded corners, and so forth, will not be deducted. The area of all
irregularly shaped Type A signs, such as U.S. and Interstate route markers,
will be measured from the dimensions of a circumscribed rectangle around the
route marker.

B. Type B Signs.

Calculated in square
feet (square meters) on the basis of area of the vertical, front face of the
signs specified in the contract documents. Measurement will not be made for
area in excess of this area.

C. Wood Posts for Type A or B Signs.

Each to the nearest
foot (0.3 m) for the various post sizes installed. When posts are placed to
depths greater than the minimum depth specified, the measured length does not
include any parts placed to depths greater than 1 foot (0.3 m) more than the
specified minimum.

D. Steel Breakaway Posts for Type A or B Signs.

1. Each
to the nearest 0.1 foot (30 mm) for the various post sizes installed.

2. Unless
specified otherwise in the contract documents, the measured length of steel breakaway
posts includes no more than 1 foot (0.3 m) over the length necessary to meet
specified minimums.

Linear feet (meters),
to nearest foot (0.3 m), measured from top of anchor to top of post. Embedded
length will not be measured separately, but included in price bid for
Perforated Square Steel Tube Posts.

H. Perforated Square Steel Tube Post Anchors.

By count of each type
installed.
